f HEAT-CONTROLLER FOR AUTOMOBILE-RADIATORS.

Patented Nov. 27, 191 '7.

Application filed nmmgmza, 1916. Serial No. 139,507.

To all whom it may concern:

Be it known that I, RUDOLPH Carlson, a sulnect of the King of Sweden, and a resident of l armingdalc, in the county of Nassau and State of New York, have invented a new and Illll'lfOVfld Hcat-Controller for AlliO11lObllORfl(llMZUIS, of which the 'lollowing is a fulh clear, and exact deconveniently and quickly attaching the heat wot-roller to i'arious types of automobiles as slow constructed,

In order to accomplish the desired result, use is madeof a light frame adapted to be attached to the vtrout of the automobile the walls of the opening llerool' a curtain movable over the front ol the radiator and attached at its lower and lmthe said frame, a roller on which radiator along winds the upper end of the curtain, support for the said roller; and operating moans coi'inected wilh the said roller frame and extending to the dashboard of the automobile to be within convenientreach of the (ll'lX'Gl to enable the latter to adjust the curtain with a view to admit more or less air to the radiator to regulate the heat within the hood. i

A. practical embodiment of the invention is represented in the accompanying draw ings forming a part-of this specification, in which similar characters of reference indicate corrcspondin parts in. all the views.

Figure 1 isncontrollcr as applied, parts bcing'shown broken out:

Fig. 2 i.- similar view (if the-same as applied to a radiator of a different shape than the one shown in Fig. 1;

Fig. 3 is a. sectional sideelevation of the heat controller in position on the radiator shown in elevation with parts in section;

Fig.4 is a side elevation of the'heat controller as applied to the radiator and dash board;

Fig. 5 is anenlarged side elevation of the, actuating mechanism of the dashboard; BVPQAGHS a cross section of the same;- and front elevation of the-heat l ig. 7 is a sectional side elevation of the same,

()n the front of the automobileradiator 10 and following the walls of the opening thereof is secured a light wire frame 11 by the use of suitable fastening devices 12 such as hm-v wiro and the like. To the bottom of the frame 11 is secured the lower end 13 of a curtain 14 winding at its upper portion on a roller 15 provided with a spring 16 and with trunnions 17 and 18 held in bearings 19 and 20 of a bracket 21. The spring 16 is attached at one end to the roller 15 and at the other end to the trunnion 18 which latter is hold stationary in the hearing 20 while the other trunnion 17 is mounted to rotate in its bearin 19. The arrangement is such that when t re bracket 21 is raised the curtain '14 unwinds from thh roller 15 and the spring 16 therefor is compressed, and when the support 21 is -lowered then the spring 16 uncoils: and

rotates the roller 15 in the reverse direcion to wind up the curtain 14. Thus by raising or lowering the bracket 21=tl1o curtain I4 is stretched over any desired portion of the radiator -front opening so as to permit morev or less or no air to pass through the radiator into the hood under which the engil'lo is located.

In order to raise or lower the bracket 21 the middle thereof is attached to one end of a cord. cable or similar flexible connection, extending upwardly and passing through a pipe 26 extending lengthwise through an opening in the radiator 10, as plainly indipor tion screws anut 28 to securely hold the pipe 27 in place on the radiator 10.

The flexible connection 25 after leaving the pipe 27 extends through the hood and winds on a drum 30 mountedin acasin 31 .attached to the front of the dashboar 32 provided with an opening 33 (see Fig. 7

l for the passage of the flexible connection 25.

41is a a ted to be locked on lugs42 formed-- on the, ace of the casing 31 next to the i5 sequent change of temperature within that,

handle 41 so as to hold the curtain 14 in adiusted position for the time being.

t is understood that automobiles as now generally, constructed are provided with motometer's to enable the driver to watch the workingof the engine and in case the engine does not work with the fullest efliciency owing, to achange in the weather and a conhood then the operator can readily adjust Ithe curtain 14, as above explained, to control the inflow of the air into the hood by way of the radiator. It is further understood that the temperature within the hood affects the working of the engine and by the arrangement described the driver is enabled to control the temperature withinthe hood to obtain the highest eiiiciency of the engine.

The portions of the radiator front openiugnot reached by the curtain 14 are "covered by a piece of screening cloth 50 attached to the frame 11, as indicated in F ,1. In case the radiator is of the shape shown in Fig. 2 then .an extra vcloth 60 is attached to the frame 11 to pro- 'vide-a rectangular! opening to be more or less covered b the curtain 14... Otherwise, the constructigii'is exactly the same as above described in reference to the curtain shown in .Fig. 1;";

Having. thus described my invention, I claim .as new and desire to secure by Letters Patent 1. The combination with an automobile radiator, a frame secured to the front,thereof and surrounding the frontopeniug of 'the same,

to the lower endof said frame, a spring roller secured to the upper end of said ourtain, a stationary screening cloth secured to the upper part of said frame and coveringpiece of screeniiig a curtainsc'cured .at its lowei eni able stationary 'screenin the radiator portion out of reach of the curtain, and a flexible eonnectioh from the sprin roller to the dashboard of the automobi said flexible: connection passin through said stationary sereenin clothftmd means on the dashboard for curtain in adjusted position in front of the radiator. f

2. In a. heat controller for' automobile radiators, consisting of a curtain secured at its lower end to t e front of the radiator, a spring end of the curtain for winding and um winding the spring roller to the dashboard of-the automobile, a stationary screening -cloth coverin e portion of the radiator outof reach 0 thecurtain, guiding means for said 3. A heat controller for automobiljradiators, comprising a curtain having its lovFer end attached 'roller on which the upper end of the said curtain winds and unw nds, means for wind- -ing and u'riw pdin said curtain, and a stationar3r;, screen1ilg c 0th mountedon thefront.

to the front of said radiator, a l 75 olding the I actuated roller secured to, the upper of said radiatpr and adapted-to cover the radiator curtain when unwound.

4. A heat controller for automobile radiators compri'sing'a stationary screening cloth detachablysecured to the front thereof and normally covering a. portion thereof, a spring roller curtain secured 'atits -lowerend at the lower end of the radiator, and adapted to be unrolled to cover the portion portions out of reach of the said of the radiator not covered by the detachficloth, and flexible means for connecting t e curtain with the dashboard of the automobile.
